Pull straight back on the drive sled handle ( 10 ) to remove it from the library (see Figure 10-7). 8. If you are replacing the tape drive sled, proceed to Installing a Tape Drive Sled for instructions. If you are not replacing the tape drive sled immediately, you must complete these procedures: a. Install a drive cover plate to protect your library from dust and debris. b. To remove the "Missing drive" indicators on the Operator Control Panel (Attention LED) and the Web User Interface (System Status screen), modify or resubmit logical library setting (Operator Control Panel: Configure > Logical Libraries or Web User Interface: Configure Library > Logical Libraries). Figure 10-7. Pulling the drive sled out of the library (drive sled without ESD springs shown) Installing a tape drive sled Note: Power OFF the library before a SCSI drive sled is installed. Fibre Channel and SAS drive sleds are hot pluggable and might be removed and installed while the library is powered ON. Important: In a 4U library a full height drive sled might be installed in drive slot 1 (drive occupies slot 1 and slot 2) or drive slot 3 (drive occupies slot 3 and slot 4). A full height drive sled must never be installed in drive slot 2 (drive occupies slot 2 and slot 3). 1. Before you install the new drive sled, inspect all connectors on the drive sled. Ensure that the connectors are intact, free of any objects, and have no cracks, or deformed or bent contacts. Chapter 10. Check, adjust, remove, and replace 10-5 a77ug027
